Be 'it known that :I, LEE P. HIYNES, a

Chicago, Cook county, Illinois, have inments' in Ventilators, ofwhich the following is a specification.

My invention relates more particularly to ventilators for cars, and in the accompanying drawing and following description is therewith; it will be obvious, however, that with or without minor modifications it may be adapted to othersimilar uses suchvas .in the ventilation of the rooms of stationary structures, etc., one such modification being also illustrated and described hereinafter.

It is Well recognized as a requirement of applied without,'however, causing the exconstituting a draft, a large cross-section being essential for the purpose. It is further; desirable that while the ventilator shall present large openings to the outer air to ac-v commodate the passage of great volumes off air,l it shall not expose the compartment to indrafts or .permit rain 'to beat into thef same. By my invention it is possible tov construct lventilators having these desired characteristics in a marked degree, and in` which the necessary suction is obtained for exhausting the aird without movable parts and under substantially all conditions .of service.

In the accompanying drawings .forming part of the application and in the detailed form or embodiment of my invention and also a modification,thereof; but itis to hel understood that the specific disclosure is for the purpose of exempliflcation'only, my invention not being limited thereto, and .I

tures and scope of the invention inthefol-V lowing claims without, however, relinquish-v ing) or dedicating any part thereof to the u lic. p Referring to the drawing, Figure 1 is aperspective of so much ofthe exterior of a car as is necessary foran understanding of my improved ventilator, showingthe latter' attached thereto; iFig. 2 is a "verticalftransverse section upon the line 2 2 of Fig. 3,'

a-nd Fig. 3 is a central longitudinally vertical section upon the line 3 3 of Fig. 2, and Fig. 4 a modification especially; adapted to an opening in a horizontal roof.

.In Fig. l the reference letter A indicates the low vertical wall between the lower deck B andlthe upper deck C of a car. Myhimy proved ventilator is shown at D applied to an openino' in a pillar between'adjacent deck sash.E-' in the' vertical wall, though, as above .indicated,vit miglitbe secured to the sash or otherwise locatedwithI reference .to

vthe-car body, or even`be used in .connection with othercompartments to y'be ventilated whether movable or stationary. As shown, it' consists in a sheet'metal construction embodying a generally horizontal yflue or air passage F, terminating at one end in a flange Gto be screwed or -otherwise secured about a Ventilating opening in the car, and at the other end in a'vertical Wall H which closes the outerend of the .flue except for upwardly and downwardlydirected branch flues J'-K which extend the entire width of the flue, as best seen in-Figs. l land 2, and

are of considerable cross section as shown in Fig. 3. The upper 'branch is.- shown as eX'- tended downwardy at J 1 some'distance into the flue, though this is'not essential, but the .lower branch terminates Hush lwith the floor L of the 'flue which slopes downwardly thereto for a purpose which will appear. Both of the flues are subdivided throughout by numerous partitions N which may be rectangularly arranged, as shown, forming a considerablenumber of smaller flues or passages. It will now be apparent that the outer ends of the branch ues are exposed more especially vto horizontal `currents of air which maybe due either to the motion of the caror other structure to vwhich they are attached or 'to the Cprevailing winds. Inl

either event the air currents passinglover and .under the upper and lower branches respectively have an' 'ejectoractiom as will be readily understood, drawing the air from the interior of Athe compartment. By reason of the numerous partition walls, each of which contributes individually to the action, 'thesuction olfset is very greatlyincreasedand any tendency'to form swirls or -eddies in the air which would interfere with the suction is avoided. In the case of vertical or inclined currents of air the device also acts with 'greatfeiiciency, any Ainclination kor lateral motion ofthe currents being 'Hue and escapesftherefrom, at the saine time exerting an ejector action on the air .within the'compart1nent...and main Hue. Furthermore, there being no direct passage int-o the compartment, there can be, no back draft due to air movements outside the car. Thisl construction also avoids rain being driven into the compartment since in order to-pass through the subdivisions of the upper Hue it must fall in a very nearly vertical direction and pass 4out the lower Hue, and any rain which does not pass directly through, is received upon the sloping Hoor L of the Hue and Hows out through branch Hue K.

The modification shown in Fig. 4 embodies the same principle of operation described in connection with .the preceding form of the device.` It comprises a central vertical Hue P having a Hange Q at its lower end-fory attachment to a substantially hori-' zontal roof formed with a Ventilating opening with which said Hue connects. At' its upper end the Hue l) communicates with an annular YHue F which in turn opens into upwardly and downwardly extending branch Hues .lL-K similar in function and operation to'the Hues J-K of the first described inoditication. A concentric disk R immediately covers the Hue P to prevent direct entrance thereto or egress .therefrom and xsaid disk is provided with a depending Harige 'R' which forms the inner wall of the annular Hue J2. Flues J 2-K are subdividedin substantially the sainemanner as,l are theHues JMK of the modiiication previously described and for a similar purpose. The operation of this form of the de vice will be apparent from what has already been-said, it being .understood that the central Hue P has the function of conveying the air to the annular Hue F from which it is drawn by the action of the Hues J2 and K.

It will be understood, of course, that the forni `of the device may bewidely varied, the two modiHcations described being, however, the preferred forms thereof.

1. A ventilator comprising a main Hue F and a branch Hue extending transversely thereto having a series of longitudinal partitions therein.'

2. A ventilator comprising a main-Hue. F

'. having means for securingit in horizontal tor/,ove

main Hue and a vertical branch Hue partially extending into the main Hue and provided with a series of longitudinally extending partitions.

4. In a ventilator, a horizontal main Hue adapted to connect at one end with the compartment to be ventilated and provided at the other end with a substantially verticalwall and a branch Hue connected to the mainV Hue and provided with a series of longitudinelly extending partitions.

' -5. A ventilator comprising a horizontal main Hueopen at one end and adapted to be connected to the compartment to be vntilated, and upwardly and downwardly extending transverse Hues at the other end of the main Hue, thev upwardly extending branch being provided with a seriesof longitudinal partitions.

6. ventilator comprising a horizontal main Hue adapted to connect at one end with acompartment to be ventilated, and upwardly and downwardly extending transverse Hues at the other end thereof, each provided with a series of longitudinally eX- tending partitions.

7. A ventilator comprising a horizontal main Hue adapted to be connected at one end with a compartment to be ventilated and closed at the other end, and upwardly and downwardly extending transverse Hues at the other end thereof, each provided with a series of longitudinally extending partitions.

8. A ventilator for cars and the like compris-ing a horizontal Hue open at one end for connection to the compartment to be ventilated and closed at its outer end, an upwardly extending branch Hue communieating with the main Hue, a downwardly extending branch Hue also communicating with the main Hue, the Hoor of the main Hue being inclined upwardly from said` LEE P. HYNES. Witnesses Louis B. Erwin, ROBERT DOBBERMAN.
